I don't doubt that you've found those statistics, as sociology is an incredibly difficult field from a methodology standpoint. Unfortunately there are problems with nearly all methodologies. There are two potential sources of the discrepancy in information here: how do you define crime, and how do you define poverty. The definition of crime has a lot of data collection problems. Official crime rates are compiled by police reports, and if there is a bias in policing or prosecution, there will be a bias in reporting as well. There are methodologies that are used (all of which with their own problems that make them suitable for some analyses but not others) to allow for better analyses to be made. It is through these alternative methodologies that we can even make claims like "black people are twice as likely to be arrested than white people for possession of marijuana": pure collection biases hide the fact that black people and white people are consuming marijuana at similar rates. The definition of poverty is also fraught, though not for systemic racism reasons. Poverty can be defined in relative terms or absolute terms. It can be based off of wealth, or it can be based off of income. It can be based on household income/wealth or individual income/wealth. It can be defined in terms economic mobility (the ability to change wealth over time), or point in time measurements. It can include social capital as well: some definitions of poverty take into account education availability, parental education levels, etc. In fact, you mention single parent households, which is deeply tied to poverty. child abandonment rates have a strong inter-causal link with poverty: high poverty causes income earners to abandon their children, and children without income earners in the household not only live in higher poverty as a result, but are likely to perpetuate the poverty. And disparate policing certainly has its own contributors to poverty, because it takes parents away from children.
